In recent years, dimethylphenol has played an important role in industrial production. The demand and application of dimethylphenol will increase greatly with the continuous advancement of the internationalization process. Solid-liquid equilibrium (SLE) is fundamental for the separation process design, the SLE data of dimethylphenol plays an important role in designing the melting and crystallization separation process. The SLE data of mixtures of 2,6-dimethylphenol (2,6-DMP), 3,5-dimethylphenol (3,5-DMP) and 2,5-dimethylphenol (2,5-DMP) were determined by differential scanning calorimetry (DSC). The crystallographic analysis of eutectic mixtures was analyzed by FTIR. The experimental results show that all the systems studied in this paper exhibit eutectic behavior. SLE data was correlated with Wilson and NRTL models and a satisfactory correlation was obtained. The study provided reliable and accurate data for separating the mixtures of 2,6-dimethylphenol, 3,5-dimethylphenol and 2,5-dimethylphenol. These SLE data are of great significance for the process development and process optimization of dimethylphenol.
